Mary Calvi  is a nine-time New York Emmy award-winning journalist and television news anchor in New York City. She is also First Lady of the City of Yonkers. Mary spent years wondering about the heiress who lived in the grand Philipse manor in her hometown. Curiosity propelled her to do extensive research poring over thousands of documents over several years. Her resulting debut novel will leave you second guessing about what you’ve known about George Washington in his youth. Prepare to be swept away into the 1700s, from breathtaking scenes of New York’s polite society to battlefield victories in Harlem and beyond. Dramatic portraits unveil a Washington on the precipice of greatness, who is also a writer of romantic poetry and a fine dancer and enamored of Westchester heiress, and Loyalist, Mary Eliza Philipse whose beauty and refinement disguise a deep and complex inner struggle. Historical figures, including Alexander Hamilton, John Jay, Daniel Boone, and Nathan Hale, help weave an intricately told story of love, deception, & vengeance.  Mary Calvi serves as a board member of the Hudson River Museum.

These authentic narratives are brought to life by actors in multimedia staged readings. The Kept Private is based on Based on an Earth Science survey of the African American burial grounds in Rhinebeck, historical documents, conversations about race in our communities, and the 1834 Revolutionary War pension application of a 93 year old black farmer from Milan named Andrew Frazier.

Erik Weiselberg, a Westchester County native, holds a Ph.D. in U.S. History from the University of Oregon (1999), and has been a social studies teacher in Westchester for over 18 years.  His scholarship has included the study of early mountaineering in Oregon’s Cascade Mountains and the German Alps, and the influence of Washington Irving on the culture and folklore of the lower Hudson River Valley. Dr. Weiselberg has served on the board of the Irvington Historical Society, and in 2011 he curated an exhibit on “The Stories of Washington Irving and the Brothers Grimm.” At Irvington High School, he developed the “Tomorrow’s Historians” Student Research Symposium which allowed young people to present their US History papers in a public forum. Last summer, he conducted research to determine which soldiers of the Revolutionary War might have lived in the area that became Irvington, and his research resulted in the addition of nine family names suitable for inclusion on the renovated Veterans’ Memorial Plaza on Main Street.  The project inspired Dr. Weiselberg to research not only the names of those who served, but the stories of everyday people other than soldiers who were active participants in the war in Westchester, including women, children, African Americans and Native Americans.
